Answer:

Area of Base = 28in^2

Area of prism = 280 in^3

Step-by-step explanation:

Area of a trapezoid:

{(a+b)/2}*h            a and b are the bases

Plug in the formula to the information:

{(9+5)/2}*4

(14/2)*4

7*4

28 in^2

Now multiply by 10 for the prism (it is 10 in tall):

28*10=280 in^3
